Abstract

In order to improve the solubility of iridium complex

at the same time exhibit high thermal stability

propylcydohexane was introduced into the main ligand to synthesize a novel red phosphorescent iridium(Ⅲ) complexe Ir(pcpiq)

acac (pcpiq=1-(4-(4-propylcyclohexyl)phenyl)isoquinoline

acac=acetylacetonate).The photophysical

thermal

and electrochemical properties of the material were investigated by UV-Vis absorption spectra

fluorescence emission spectra

differential scanning calorimetry (DSC) and cyclic voltammetric method. Additionally

the synthesized iridium(Ⅲ) complex was used as a red light-emitting dopant material with 4~12% doping concentration in emissive layer to fabricate organic light-emitting diodes (OLED) by vacuum deposition or spin-coating method. The test results showed that the OLED by vacuum deposition obtained an electroluminescence (EL) maximum at 639 nm

a maximum current efficiency of 6.11 cd/A

a maximum power efficiency of 1.64 lm/W

and a pure red color with the CIE coordinates of (0.68

0.32)

when Alq

was used as the host material.
